Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 In this invention, a disposable flexible tube is attached to the suction hose of a vacuum cleaner as needed on the inner circumference of the suction hose to create a suction gap for collecting dirt and other viscous substances from the flexible tube. About the provided hose.

[0002]

[Prior art]

 It is possible to collect the residual ink for printing or the waste discharged by the sick person by using the suction hose of an ordinary vacuum cleaner, but the suction hose itself becomes dirty and becomes an obstacle to re-use.

[0003]

[Problems to be solved by the invention]

 This invention provides a hose in which a disposable tube attached by suction is attached to the inner peripheral portion of a suction hose of a vacuum cleaner, and a suction gap for discarding only the disposable tube after use is provided.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a suction gap is opened between an outer cylinder of a suction hose of a vacuum cleaner and an inner peripheral surface of the cylinder, and a disposable soft having an outer diameter corresponding to the inner peripheral diameter of the cylinder. The tube is detachably mounted, and a strong suction force can be obtained in the flexible tube in a state where the flexible tube is brought into close contact with the inner peripheral surface of the suction hose by the suction air from the suction gap.

[0005]

[Embodiment of the invention]

 A suction gap is opened between the outer cylinder of the suction hose of the vacuum cleaner and the inner peripheral surface of the cylinder, and a disposable flexible tube having an outer diameter corresponding to the inner peripheral diameter of the vacuum hose is detachably mounted. With the flexible tube tightly attached to the inner peripheral surface of the suction hose by suction air from the suction gap, a strong suction force is obtained in the flexible tube to collect viscous dirt and used viscous ink.

【Example】

 Hereinafter, embodiments will be described with reference to the drawings. The outline of the liquid and viscous material recovery hose will be described with reference to the accompanying drawings. The suction hose 1 of the vacuum cleaner having flexibility and the suction hose have a narrow groove-shaped suction gap 3 formed in the inner circumferential surface 2 of the cylinder in the longitudinal direction, and correspond to the inner diameter of the suction hose 1. A disposable flexible tube 4 having an outer diameter is detachably mounted. The flexible tube 4 is, for example, an elongated cylindrical body made of a polyethylene film. During the suction operation, suction air is obtained from the suction gap to bring the flexible tube 4 into close contact with the inner peripheral surface 2 of the suction hose. The inner diameter of the suction hose 1 is appropriately determined depending on the type of the viscous material to be collected.

In the above embodiment, the suction gap 3 is formed in the inner peripheral surface of the suction hose 1 in a narrow groove shape in the longitudinal direction for sucking the flexible tube 4. As long as the tube 4 is brought into close contact with the inner peripheral surface of the suction hose 1, a large number of suction pores provided on the inner peripheral surface 2 of the suction hose may be used.

Next, the front portion 6 of the flexible tube 4 is extended from the front end portion 5 of the suction hose 1 of the vacuum cleaner, and the front portion is turned back to the front end portion 5 of the suction hose 1. To the front end 5 of the suction hose 1. The rear end of the suction hose 1 is fitted into the hose insertion tube portion 15 of the pail container 11 and is opened inside the pail container 11.

On the other hand, the pail container 11 and the vacuum compressor 13 are connected by a suction pipe 12. When the open / close cock 8 closes the suction provided at the distal end of the suction hose 1, the flexible tube 4 that is in close contact with the inside of the pail can holder 11 and the inner circumferential surface 2 of the suction hose is closed. The space of the interior 9 forms a completely closed state. In this state, when the vacuum pump is operated and the opening / closing cock 8 is opened, strong suction is performed to suck the liquid and the viscous material a from the suction fitting 14 attached to the front end 5 of the suction hose 1. Is done. Air volume sufficient to suck the liquid and viscous substance is sufficient ^{2.86mm 3 / min ~2mm 3 / min} .

That is, by performing the above suction operation, strong suction is obtained from the suction end of the suction hose 14 at the tip end of the suction hose 1, so that the waste ink is absorbed and the remaining printing ink is used by the sick person, The viscous material such as the used viscous ink passes through the inner portion 9 of the disposable flexible tube 4 and is discharged from the other end discharge port 10 of the flexible tube 3 to the pail container 11.

Since the suction fitting 14, the disposable flexible tube 4, and the pail can storage container 11 through which the viscous material passes are contaminated by the viscous material that has passed, the suction fitting 14 and the pail can storage container 11 are also removed as soon as possible. At the same time, the disposable flexible tube 3 is withdrawn from the suction hose 1 immediately after use and discarded to prepare for the next hygienic use.

For example, when recovering the remaining ink used for screen printing, gravure printing, offset printing, etc. in preparation for the next use, by performing the collecting operation separately for each different ink color, different types of ink can be obtained. Therefore, the same ink can be collected without difficulty by avoiding the mixing of ink.

Although not shown, a vacuum cleaner used for business purposes can also be used without using the vacuum compressor 13.

[0013]

[Effect of the invention]

 In the hose having the suction gap according to the first aspect, the suction gap is opened between the outer cylinder and the inner peripheral surface of the suction hose of the vacuum cleaner, and has an outer diameter corresponding to the inner diameter of the cylinder. A disposable flexible tube is detachably mounted, and a strong suction force can be obtained in the flexible tube in a state where the flexible tube is brought into close contact with the inner peripheral surface of the suction hose by suction air from the suction gap. Therefore, it is possible to easily attach a flexible tube inside the outer cylinder of the suction hose, collect the viscous material, and then remove the flexible tube and discard it. Moreover, since the suction hose is not contaminated during the collection operation, complicated cleaning work can be minimized and the collection of the contaminants such as dirt and viscous ink can be performed hygienically and quickly. .
